Which species is known as the cabbage aphid?

The cabbage aphid is specifically identified as Brevicoryne brassicae, a species that predominantly feeds on plants in the Brassicaceae family, which includes cabbage, broccoli, and other cruciferous vegetables. This aphid is known for its characteristic light green coloration and the presence of a waxy coating that can give a glistening appearance.

Understanding the impact of Brevicoryne brassicae is crucial for managing pest populations in agricultural settings, especially for crops in the cabbage family. It can cause significant damage by feeding on plant sap, which not only stunts growth but may also lead to secondary issues such as the spread of plant viruses.

In contrast, the other species mentioned—Myzus persicae (green peach aphid), Aphis gossypii (cotton aphid), and Acyrthosiphon pisum (pea aphid)—are known for their association with different plants and agricultural impacts. While these aphids are important pests in their own right, they do not possess the specific association with cabbage and other brassicas that defines Brevicoryne brassicae. This highlights the importance of correctly identifying pest species for effective management.
